Research Overview
Argireline
Acetyl hexapeptide-3 has both in vitro and small human-cosmetic studies supporting a reduction in wrinkle depth or wrinkle appearance. Its best-supported role is as a topical cosmetic peptide rather than a systemic drug.
Hexapeptide-9
Hexapeptide-9 appears in scientific and cosmetic literature related to wound repair, cell migration, and extracellular matrix support. The evidence base is smaller than for more established peptides, but it is a real research-backed cosmetic ingredient.
